Dual-Element Instrument Microphone
The Artist Series new kick-drum mic, the ATM250DE dual-element instrument microphone features cardioid condenser and hypercardioid dynamic capsules combined in a single housing. Audio-Technica's innovative use of 2 polar patterns is ideal for kick drum: the hypercardioid dynamic element focuses tightly on the aggressive attack of the beater, while the condenser captures the round tonalities of the shell. The elements are positioned in a perfect phase relationship, something practically impossible to achieve with two separate microphones. Includes a professional isolation clamp to provide secure mounting, versatile positioning and effective dampening of unwanted mechanical noise.
Features:
Audio-Technica's proven dual-element design features 2 elements (condenser and dynamic) enclosed in a single housing
Neodymium dynamic element provides punch and attack, while the condenser element captures the full audio spectrum
Elements are positioned in a perfect phase relationship, something practically unachievable with 2 separate microphones
Perfect for kick drum, guitar amps and instrument use
Integral 80 Hz HPF switch and 10 dB pad (condenser element)
Versatile mounting options and effective dampening of mechanical noise thanks to included AT8471 isolation clamp
Corrosion-resistant contacts from gold-plated XLRM-type connector
Rugged, all-metal design and construction for years of trouble-free use
The ATM250DE is intended for use in professional applications where remote power is available. It requires 11V to 52V DC phantom power only to the condenser output of the supplied cable.
Output from the microphone's 5-pin XLRM-type connector is low impedance (Lo-Z) balanced.The included 5.0 m (16.5') shielded cable features a 5-pin XLRF-type input connector and 2 standard 3-pin XLRM-type output connectors. The balanced signals appear across Pins 2 and 3 (condenser) and Pins 4 and 5 (dynamic).Pin 1 is ground (shield). Output is phased so that positive acoustic pressure produces positive voltage at Pins 2 and 4.
To avoid phase cancellation and poor sound, all mic cables must be wired consistently:Pin 1-to-Pin 1, etc.
An integral 80 Hz hi-pass filter on the condenser element provides easy switching from a flat frequency response to a low-end roll-off.The roll-off position reduces the pickup of low-frequency ambient noise (such as traffic, air-handling systems, etc.), room reverberation and mechanically-coupled vibrations.
The ATM250DE's condenser element is also equipped with a switchable 10 dB pad that lowers the microphone's sensitivity, thus providing higher SPL capability for flexible use with a wide range of performers and system configurations.
The ATM250DE includes an AT8471 isolation clamp to provide secure mounting, versatile positioning and effective dampening of unwanted mechanical noise.
Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110 degreesF (43 degreesC) for extended periods. Extremely high humidity should also be avoided.Take care to keep foreign particles from entering the windscreen.An accumulation of iron or steel filings on the diaphragm, and/or foreign material in the windscreen's mesh surface, can degrade performance.
Artist Series Microphones
Audio-Technica's renowned Artist Series has been re-engineered from the ground up. They've packed the culmination of 40-plus years of research and design into the rebirth of these road-proven, reliable designs -- adding some spectacularly innovative microphones to the line, and upgrading classic models for a complete selection of vocal, instrument and drum mics.
This first-ever remake of the Artist Series was inspired by consultations with touring artists and sound engineers who rely on these microphones for rock-solid performance night after night. Our engineers turned their what if's into why not's. Why not create a dual-element kick drum mic that the working musician can afford? Or a pencil side-address condenser built for incredibly flexible placement options? What about adding a durable vocal condenser to the Artist Series family? And while they're at it, why not include a generous selection of real-world accessories that make these microphones easy to use on a clutter-free stage. We are proud to have made these and more dreams for this series a reality.
The sound is everything you'd expect from Audio-Technica. The vocal mics set industry standards for intelligibility, detailed reproduction and noise suppression. The new instrument microphones feature a fast transient response and low distortion characteristics that faithfully reproduce the complex details of virtually every sound source. For the drums, Audio-Technica built on the legacy of its legendary AE2500, and introduced the new ATM250DE, a dual-element kick-drum microphone that combines 2 perfectly positioned capsules in a single housing.
Whether you use wedges or in-ears, line-array or portable PA, the Artist Series will help you squeeze every ounce of performance out of your reinforcement system. Plus they're built tough. As the company that made studio condensers durable enough for stage use, Audio Technica knows a thing or 2 about solid construction. The Artist Series is rugged to the core -- these all-metal microphones are engineered to perform flawlessly despite the inevitable bumps and bruises of life on the road.
These microphones are created to bring clear sound, rock-solid durability and aesthetic design to every stage where artists and audiences connect... from corner bars to Carnegie Hall. Meet the Artist Series. New, again, from Audio-Technica, the pioneer in high-performance transducer design.
